OVILA BAIGNE, OF MONTREAL, QUEBEC, CANADA.

FOLDING BED.

To all whom it may concern:

Be it known that I, OVILA BAIeNi, a subject of the King of GreatBritain, residing at 19 St. George street, in the city and district ofMontreal, in the Province of Quebec, in the Dominion of Canada, haveinvented certain new and useful Improvements in Folding Beds, of whichthe following is a specification.

The invention relates to improvements in folding beds, as described inthe present specification and illustrated in the accompanying drawingsthat form part of the same.

he invention consists essentially of the novel arrangement andconstruction of parts, whereby in the operation of opening the bed, theweight is transmitted through an independent supporting member to apoint to the rear of the fixed journal bearing.

The objects of the invention are to devise a folding bed in which theweight may be materially reduced as compared with the casing type of bedcommonly in use, to cheapen the construction of such furniture, and toprovide a simple mechanism easily operated and adjuste In the drawings,Figure 1 is a perspective view of the bed open. Fig. 2 is a frontelevation showing the bed closed. Fig. 3 is a side elevation showing thecasing in section. Fig. 4 is a rear elevation showing the casing insection. Fig. 5 is a perspective detail of the suspension member. Fig. 6is a perspective detail of the operating spring arrangement in theclosed position of the bed. Fig. 7 is a perspective detail of theoperating spring arrangement in the open position of t e bed.

Like numerals of reference indicate corre sponding parts in each figure.

Referring to the drawings, 1 is an up-right casing, here shown as havingthe sides 2, the top 3, bottom 4 and back 5, the latter closing in therear of said casing. The front of said casing is completely open.

6 is a suspension member formed of the bars 7, having the journalorifices S at the lower end thereof and the pivot holes 9 at the upperend, the rod 10, journaled in the said orifices 8 and having the squaredends 11 projecting beyond the outer face of the said bars 7, and thearms 12 fixedly secured on the squared ends 11 of the rod 10.

13 is a helical spring encircling the rod 10 and fixedly secured at oneend to a bar 7 and Specification of Letters Patent.

at the other end to the adjusting nut 14, the outer member of saidadjusting nut being fixedly mounted on the rod 10.

15 are pivot pins securing the said bars 7 through the pivot holes 9 tothe inside face of the sides 2 at the rear corner thereof, said barsextending downwardly inside said casing and supporting the said rod 10just above the bottom 4. The helical spring 13 is so adjusted as tocause the arms 12 to spring inwardly towards the back 5 withconsiderable force.

16 is the bed here shown as made on the back of a box forming thecupboard 17, the the outer legs of the bed in its lower position.cornice pieces 18 of said cupboard forming The arrangement of a cupboardto the front of the bed in its closed position is only a convenience,and in fact is only one form of construction, as many other arrangementsmay be shown or a simple closed in box bed, but in order to make it auseful as well as an ornamental piece of furniture, the on )board 17 issuggested as a particularly applicable form, to which is added the door19 closing in the lower portion of the structure under said cupboard andforming also a convenient receptacle for boots and other articles ofwear not placed in the cupboard thereabove.

20 are pins projecting laterally from the box sides of said bed adjacentto the center of each side, and 21 are rollers journaled on the saidpins 20, the said arms 12 from the suspension members 6 extending undersaid rollers 21.

22 are pedestals fixedly secured in the easing 1 immediately in front ofthe rod 10.

24 are bearings formed in the pedestals 22 intermediate of their height.

25 are shaft ends extending laterally from the box supporting the bed atthe rear corners thereof and j ournaled in the bearings 24, the saidbearings and said pedestals being so arranged that the bed and box inits vertical position will be inclosed within the casing 1.

It has already been explained that the arms 12 extend under the rollers21, therefore there is a continuous strain on the said suspension member6 and as the said suspension member includes also the means offacilitating the folding of the bed, that is to say, the spring, theweightof said bed in opening will be transmitted by the downward pull tothe pivot points of said bars 7 in their upper end and thus obviate theannoyances and dangers incident to the upsetting and falling of thecasing which occurs in many of such devices.

In the operation of the bed, what may be called the front side of thecupboard is pulled outwardly, which brings out the complete box bed, thelatter turning in the bearings 24 and being supported by the arms 12.The arms 12 as has been explained hereinbefore have a tendency to springrearwardly towards the back of the casing 1, consequently as the bedmoves downwardly, the rollers 21 travel along said arms. In the actionof pulling the bed its own weight in its downward movement iscontinuously against the upward and rearward spring pressure of the saidarms 12.

The weight of the bed in its downward movement is thus transmittedthrough the said arms to the bars 7 where the said weight pulls downwardfrom the pivotal points of said bars. By this arrangement the casing 1stands firmly on its base because the weight of the bed in operation iscontained entirely therewithin and to the rear of the journal bearingson which said bed swings.

The advantages of this invention have been to some extent set forth inthe first part of the specification, but it may also be stated that indevices of this kind it has heretofore been necessary to make thecasings of a very heavy and cumbersome nature, in order that they maywithstand the act of lowering the bed, without upsetting, but in thisinvention, the casing may be made of light weight and handsome material,thus making it easy to transport and much cheaper to manufacture. Thesame arrangement of suspension, of course may be applied in other typesof folding beds where there is no casing but it is considered as beingmore generally applicable to folding beds having a casing.

The suspension bars being pivoted at the up er end of the casingadjacent to the rear wal thereof, permit a slight outward swing at theirlower ends in the opening of the bed, which relieves any jar on thecasing incidental to a rigidly supported bearing, for it is, of course,at the lower end of the said rods that the bed has its inner bearing.This very slight swing of the bearing merely compensates for that firstjerk or movement of the casing, usual to such structures, but inbringing the weight of the bed down, the lever arms 12 do not supportthat weight, because of the longer leverage of the suspension bars 7.

What I claim as my invention is:

1. In a folding bed, the combination with suitable supports and a bedhaving shaft members extending laterally therefrom towards one endthereof and journaled in said supports, of a suspension member pivotallysecured at its upper ends having shorter arms engaging said bed andtransmitting the weight of the latter in opening to the rear of the saidjournaling, substantially as described.

2. In a folding bed, the combination with suitable supports and a bedhaving shaft members extending laterally therefrom to wards one endthereof and journaled in said supports, of an independent supportingmember having shorter arms pivotally connected therewith and fastened atits upper ends and engaging said bed and transmitting the weight of thelatter in opening to the rear of the said journaling, substantially asdescribed.

3. In a device of the class described, a bed supported and swinging infixed bearings and an independent tension member suitably fastened atits upper ends and lending support to said bed and taking through itsshorter pivoted arms the weight in swinging and transmitting said weightto the rear of the fixed bearings, substantially as described.

4. In a folding bed, the combination with an open front vertical casingand fixed bearings at the lower end thereof, of a bed structure havingshaft ends extending laterally therefrom at one end thereof andjournaled in said fixed bearings, and a suspension member secured at itsupper ends inside said casing to the rear thereof and having a springrotated part at its lower end from which extendss orter arms engagingsaid bed, substantially as described.

5. In a folding bed, the combination with an open front vertical casingand fixed bearings at the lower end thereof, of a bed structure, and' asuspension member formed of vertical bars pivotally suspended withinsaid casing to the rear thereof, a spring rotated rod journaled at thelower ends of said bars, and arms of shorter length than said verticalbars fixedly secured to the outer ends of said rod, the latter engagingsaid bed, substantially as described.

6. In a folding bed, the combination with an open front vertical casingand fixed bearings at the lower end thereof, of a bed structure, and asuspension member formed of bars vertically arranged inside said casingto the rear thereof, a rod journaled at the lower end of said bars andarms of shorter length than said vertical bars extending from the endsof said rod and engaging said bed, and a helical spring encircling saidrod and secured to one of said vertical bars at one end and at the otherend to an adjusting nut mounted on said rotating rod, substantially asdescribed.

7. In a device of the class described, in combination, a vertical casingopen at the front, pedestals fixedly secured within said casing andhaving bearings arranged therein, a bed structure having shaft endsextending laterally therefrom at one end journaled in said bearings androller members extending from the sides thereof adjacent to the centersecured to the other end of said helical spring, substantially asdescribed.
